Description

本願発明は、緯入れに必要な緯糸を巻付け、緯糸を所定のピッチで貯留する緯糸送り機構を備えた緯糸測長貯留装置の緯糸送り羽根調整工具に関する。   The present invention relates to a weft feed blade adjustment tool for a weft length measuring and storage device provided with a weft feed mechanism for winding a weft necessary for weft insertion and storing the weft at a predetermined pitch.

緯糸測長貯留装置の貯留ドラムに巻き付けられる緯糸は、緯糸間のピッチが一定にならず、緯糸間隔に広狭のばらつきが生じ易い。緯糸間隔が狭い場合、隣接する緯糸が相互に重なり易く、また、緯糸間隔が広い場合、緯糸の引き出し側に緯糸が詰まり、緯糸が重なり易くなる。緯糸が相互に重なると、緯糸の引き出し抵抗が増加し、緯入れ不良を発生する大きな要因となる。また、巻き付けられた複数の緯糸がリング状の束になって貯留ドラムから抜け落ち、緯入れノズルに詰まるか、織機に備えられている機構の一部に引っ掛かり、緯入れ不能となる恐れがある。   In the weft wound around the storage drum of the weft length measuring storage device, the pitch between the wefts is not constant, and wide and narrow variations are likely to occur in the weft intervals. When the weft interval is narrow, adjacent weft yarns tend to overlap each other, and when the weft interval is wide, the weft yarns are clogged on the weft draw side and the weft yarns easily overlap. When the wefts overlap each other, the weft pull-out resistance increases, which is a major cause of poor weft insertion. In addition, a plurality of wound wefts may be bundled in a ring shape and fall out of the storage drum and get stuck in the weft insertion nozzle or may be caught by a part of the mechanism provided in the loom and become unable to be inserted.

このような緯糸間隔のばらつきを抑制するため、緯糸送り機構を備えた緯糸測長貯留装置が知られている。緯糸送り機構は、緯糸送り羽根を、貯留ドラムに設けた半径方向に貫通する複数の挿通孔から貯留ドラムの外周側に突出させるとともに、緯糸引き出し方向に移動した後、貯留ドラムの内部に没入させるように構成されている。緯糸送り羽根は、突出時に、貯留ドラムに巻かれた緯糸を緯糸引き出し方向に送り、緯糸を貯留ドラムに一定のピッチで巻き付けることができる。   In order to suppress such a variation in the weft interval, a weft length measuring and storing device having a weft feeding mechanism is known. The weft feed mechanism causes the weft feed blades to protrude from the plurality of insertion holes penetrating in the radial direction provided in the storage drum to the outer peripheral side of the storage drum, and after moving in the weft draw-out direction, is immersed in the storage drum It is configured as follows. When protruding, the weft feed blade can feed the weft wound around the storage drum in the weft drawing direction and wind the weft around the storage drum at a constant pitch.

緯糸送り機構を備えた緯糸測長貯留装置において、織成条件の変更に伴い緯糸測長量を変更する場合、貯留ドラムの径を変更するとともに、緯糸送り羽根を貯留ドラムの径方向に変更する必要がある。例えば、特許文献１には、緯糸測長貯留装置に目盛板を設けておき、貯留ドラム及び緯糸送り羽根を目盛に合わせて調整する構成が開示されている。   In a weft length measuring and storage device equipped with a weft feed mechanism, when changing the weft length measurement amount in accordance with the change of weaving conditions, the diameter of the storage drum is changed and the weft feed blade is changed in the radial direction of the storage drum. There is a need. For example, Patent Document 1 discloses a configuration in which a scale plate is provided in the weft length measuring storage device, and the storage drum and the weft feed blade are adjusted according to the scale.

具体的には、静止状態に保持されるドラムホルダーに対し４つに分割された測長ドラム片をそれぞれ半径方向への位置調整可能に取付ける。また、ドラムホルダーの表面に対し測長ドラム片の位置調整用の第１目盛板を設ける。静止状態に保持される取付けプレートに対し送り羽根を半径方向への位置調整可能に取付ける。さらに、取付けプレートの前面に送り羽根の位置調整用の第２目盛板を設ける。そして、測長ドラム片の位置に適した各送り羽根の位置を両目盛板により調整する。   Specifically, the length measuring drum pieces divided into four pieces are attached to the drum holder held in a stationary state so that the position in the radial direction can be adjusted. Further, a first scale plate for adjusting the position of the length measuring drum piece is provided on the surface of the drum holder. A feed blade is attached to a mounting plate held in a stationary state so that its position in the radial direction can be adjusted. Further, a second scale plate for adjusting the position of the feed blade is provided on the front surface of the mounting plate. And the position of each feed blade suitable for the position of the length measuring drum piece is adjusted by both scale plates.

Further, the length measuring drum piece is divided into a plurality of pieces as disclosed in Patent Document 1 as four pieces. For this reason, the feed blade must be set to the same protruding amount in each length measuring drum piece.

特許文献１では、作業者は、取付けプレートの前面に設けられた第２目盛板を見ながら送り羽根の突出量を規定値に合うように調整しなければならない。また、作業者は他の各測長ドラム片において、第２目盛板を見ながら、送り羽根の突出量をそれぞれ同一となるように調整しなければならない。しかし、送り羽根の突出量は各測長ドラム片においてばらつき易く、その結果、各測長ドラム片において、緯糸の送り量にばらつきが生じ、貯留ドラムに巻き付けられた緯糸間隔に広狭を生じる問題がある。   In Patent Document 1, the operator must adjust the protruding amount of the feed blade to a specified value while looking at the second scale plate provided on the front surface of the mounting plate. Further, the operator must adjust the protruding amount of the feed blade to be the same while looking at the second scale plate in each of the other measuring drum pieces. However, the protruding amount of the feed blade is likely to vary in each length measuring drum piece, and as a result, in each length measuring drum piece, the weft feed amount varies, and there is a problem that the distance between the wefts wound around the storage drum is wide or narrow. is there.

（第１の実施形態）
図１〜図６に示した第１の実施形態は、エアジェット織機に使用する緯糸測長貯留装置の緯糸送り羽根調整工具を示すものである。図１〜図３において、緯糸測長貯留装置の構成を説明する。フレーム（図示せず）に回転可能に軸受された中空の回転軸１は、回転軸１と交差する方向に延出する中空の緯糸巻付け管２を備える。回転軸１及び緯糸巻付け管２は中空部が連通しており、図示しない給糸部から引き出された緯糸Ｙが引き通されている。回転軸１には、大径の円板部３を備えた支持体４が軸受５を介して相対回転可能に取付けられている。 (First embodiment)
1st Embodiment shown in FIGS. 1-6 shows the weft feed blade adjustment tool of the weft length measuring storage apparatus used for an air jet loom. 1 to 3, the configuration of the weft length measuring storage device will be described. A hollow rotating shaft 1 rotatably supported by a frame (not shown) includes a hollow weft winding tube 2 extending in a direction intersecting with the rotating shaft 1. The rotary shaft 1 and the weft winding tube 2 communicate with each other through a hollow portion, and a weft Y drawn from a yarn supply portion (not shown) is passed therethrough. A support 4 having a large-diameter disk portion 3 is attached to the rotary shaft 1 via a bearing 5 so as to be relatively rotatable.

緯糸Ｙの貯留ドラム６は４片の弧状に形成された測長バンド７を環状に配列することにより構成されている。測長バンド７は、鉄系材料の表面にクロムメッキ処理した１枚の均一な厚みの弧状の板材で構成され、Ｌ字型に屈曲させた平板部８と、緯糸巻付け管２から供給される緯糸Ｙが巻き付けられる案内部９と、巻き付けられた緯糸Ｙが貯留される貯留部１０とを有する。各測長バンド７の平板部８は、半径方向の位置調整を可能にする長孔１１（図２参照）においてボルト１２により支持体４の円板部３に固定される。各測長バンド７の半径方向への調整位置は、円板部３に刻設された目盛５６によって位置決めされる。   The storage drum 6 of the weft Y is constituted by arranging length measuring bands 7 formed in an arc shape in four pieces in an annular shape. The length measuring band 7 is composed of one sheet of an arc-shaped plate having a uniform thickness that is chrome-plated on the surface of an iron-based material, and is supplied from a flat plate portion 8 bent in an L shape and a weft winding tube 2. A guide unit 9 around which the weft Y is wound, and a storage unit 10 in which the wound weft Y is stored. The flat plate portion 8 of each length measuring band 7 is fixed to the disc portion 3 of the support 4 by a bolt 12 in a long hole 11 (see FIG. 2) that enables radial position adjustment. The adjustment position of each length measuring band 7 in the radial direction is determined by a scale 56 engraved on the disc portion 3.

測長バンド７の形状は、平板部８の外周側が貯留ドラム６の周方向に湾曲し、平板部８の外周側を頂点として、湾曲面で形成された案内部９が回転軸１の中心軸線Ｘ１に向けて傾斜している。従って、緯糸巻付け管２によって案内部９の外周面に巻き付けられた緯糸Ｙは案内部９の傾斜面を順次滑落していく。   The shape of the length measuring band 7 is such that the outer peripheral side of the flat plate portion 8 is curved in the circumferential direction of the storage drum 6, and the guide portion 9 formed of a curved surface with the outer peripheral side of the flat plate portion 8 as a vertex is the central axis of the rotary shaft 1. Inclined toward X1. Therefore, the weft Y wound around the outer peripheral surface of the guide portion 9 by the weft winding tube 2 sequentially slides down the inclined surface of the guide portion 9.

貯留部１０はその外周に案内部９の最小径部と同一の曲率半径の湾曲面を有し、案内部９に連続して回転軸１の中心軸線Ｘ１に平行となるように、緯糸Ｙの引き出し方向に延出されている。貯留部１０には、図２に示されるように、貯留ドラム６の半径方向に貫通し、かつ緯糸Ｙの引き出し方向に延びる複数の挿通孔１３が穿設されている。挿通孔１３はさらに案内部９の一部まで延びている。また、各測長バンド７において各挿通孔１３は図２のように、貯留ドラム６の周方向に２列等間隔で配置されている。なお、挿通孔１３は全て等間隔に配列して穿設することも可能である。案内部９を滑落した緯糸Ｙは貯留部１０の挿通孔１３の外周面に列状に貯留される。なお、貯留部１０の外周面は緯糸Ｙの引き出し方向に若干縮径あるいは拡径する傾斜面で形成することも可能である。   The storage portion 10 has a curved surface with the same radius of curvature as the minimum diameter portion of the guide portion 9 on the outer periphery thereof, and is continuous with the guide portion 9 so as to be parallel to the central axis X1 of the rotary shaft 1. It extends in the pull-out direction. As shown in FIG. 2, a plurality of insertion holes 13 that penetrate in the radial direction of the storage drum 6 and extend in the direction in which the weft Y is pulled out are formed in the storage unit 10. The insertion hole 13 further extends to a part of the guide portion 9. Further, in each length measurement band 7, the insertion holes 13 are arranged at equal intervals in two rows in the circumferential direction of the storage drum 6 as shown in FIG. 2. Note that all the insertion holes 13 can be arranged at equal intervals. The wefts Y that have slid down the guide portion 9 are stored in a row on the outer peripheral surface of the insertion hole 13 of the storage portion 10. Note that the outer peripheral surface of the storage portion 10 can also be formed as an inclined surface that is slightly reduced in diameter or expanded in the drawing direction of the weft Y.

回転軸１の先端側（図１の右側）に位置する小径軸１４には、緯糸送り機構１５の駆動部を構成するスリーブ１６が嵌合され、ボルト１７により固定されている。スリーブ１６はその偏心軸線Ｘ２が回転軸１の中心軸線Ｘ１に対して偏心するとともに緯糸Ｙの引き出し方向に傾斜した形状で構成されている。スリーブ１６の外周面には、フランジを有する取付け筒１８が軸受１９を介して相対回転可能に嵌合されている。取付け筒１８のフランジには、取付けプレート２０がボルト２１により固定されている。取付けプレート２０の中心部は取付け筒１８を覆う蓋の役目をしている。   A sleeve 16 that constitutes a drive unit of the weft feed mechanism 15 is fitted to a small diameter shaft 14 that is located on the distal end side (right side in FIG. 1) of the rotary shaft 1 and is fixed by a bolt 17. The sleeve 16 has a shape in which the eccentric axis X2 is eccentric with respect to the central axis X1 of the rotary shaft 1 and is inclined in the drawing direction of the weft Y. A mounting cylinder 18 having a flange is fitted to the outer peripheral surface of the sleeve 16 via a bearing 19 so as to be relatively rotatable. A mounting plate 20 is fixed to the flange of the mounting cylinder 18 with bolts 21. The central portion of the mounting plate 20 serves as a lid that covers the mounting cylinder 18.

取付けプレート２０の外側面には、各測長バンド７に対応した４つの取付けブラケット２２がボルト２３により固定される。取付けブラケット２２はアルミ系材料で鉤型に形成され、垂直部２４を半径方向の位置調整が可能なように２列形成した長孔２５（図３参照）を介して取付けプレート２０に固定され、水平部２６に６枚の緯糸送り羽根２７がそれぞれボルト２８及びナット２９により固定されている。   Four mounting brackets 22 corresponding to the respective measurement bands 7 are fixed to the outer surface of the mounting plate 20 by bolts 23. The mounting bracket 22 is formed in a bowl shape with an aluminum-based material, and is fixed to the mounting plate 20 through long holes 25 (see FIG. 3) in which the vertical portions 24 are formed in two rows so that the radial position can be adjusted. Six weft feed blades 27 are fixed to the horizontal portion 26 by bolts 28 and nuts 29, respectively.

緯糸送り羽根２７はＵ字状に形成され、２枚一組として形成されている。なお、緯糸送り羽根２７の形成は単独の板、あるいは３枚以上を１つの部材で形成することも可能である。緯糸送り羽根２７を形成するＵ字状部材はステンレス鋼をプレス加工することにより成型され、その表面全体が窒化処理されている。各緯糸送り羽根２７は貯留ドラム６の内側で各測長バンド７の挿通孔１３に対向して配置され、測長バンド７の外周に出没する。   The weft feed blade 27 is formed in a U shape and is formed as a set of two sheets. The weft feed blade 27 can be formed as a single plate or three or more pieces as a single member. The U-shaped member forming the weft feed blade 27 is formed by pressing stainless steel, and the entire surface thereof is nitrided. Each weft feed blade 27 is disposed inside the storage drum 6 so as to face the insertion hole 13 of each length measuring band 7, and appears and disappears on the outer circumference of the length measuring band 7.

支持体４には、リング３０がボルト３１によって固定されており、リング３０の外周面と取付け筒１８のフランジの外周面との間に、ゴムや樹脂等の可撓性材料で構成された遮蔽筒３２の両端部がそれぞれ嵌合され、締付バンド３３によって固定されている。遮蔽筒３２は前後方向への弾性変形及び半径方向への弾性変形が可能で、円周方向へ捻る力に対しては抵抗力を有し、支持体４と取付け筒１８の相対回転が阻止される。   A ring 30 is fixed to the support 4 by bolts 31, and a shield made of a flexible material such as rubber or resin is provided between the outer peripheral surface of the ring 30 and the outer peripheral surface of the flange of the mounting cylinder 18. Both ends of the tube 32 are fitted and fixed by a fastening band 33. The shielding cylinder 32 can be elastically deformed in the front-rear direction and elastically deformed in the radial direction, has resistance against the twisting force in the circumferential direction, and the relative rotation of the support 4 and the mounting cylinder 18 is prevented. The

貯留ドラム６を構成する４つの測長バンド７のうち、上方に配置された測長バンド７には、貯留部１０の緯糸引き出し側の外周面に有底の挿入孔３４が形成されている。挿入孔３４は電磁ソレノイド３５により作動する電磁ピン３６の進入、退出を許容し、緯糸Ｙの引き出しを制御する。なお、挿入孔３４は貯留部１０の外周面から内周面に抜ける貫通孔で形成してもよい。貯留ドラム６には、支持体４の円板部３の外周に複数の永久磁石３７が設けられている。永久磁石３７は図示しないフレームに固定されたカバー３８に設けられた複数の永久磁石３９と対向するように設けられ、永久磁石３７と永久磁石３９との吸引力により、貯留ドラム６が回転軸１の回転に対して静止状態に維持される。   Of the four length measuring bands 7 constituting the storage drum 6, the length measuring band 7 disposed above has a bottomed insertion hole 34 formed on the outer peripheral surface of the storage portion 10 on the weft drawing side. The insertion hole 34 allows entry and withdrawal of the electromagnetic pin 36 operated by the electromagnetic solenoid 35 and controls the withdrawal of the weft Y. The insertion hole 34 may be formed as a through-hole that extends from the outer peripheral surface of the storage unit 10 to the inner peripheral surface. The storage drum 6 is provided with a plurality of permanent magnets 37 on the outer periphery of the disc portion 3 of the support 4. The permanent magnet 37 is provided so as to face a plurality of permanent magnets 39 provided on a cover 38 fixed to a frame (not shown), and the storage drum 6 is rotated by the attraction force between the permanent magnet 37 and the permanent magnet 39. It is kept stationary with respect to the rotation of.

図４〜図６において、緯糸送り羽根調整工具４０の構成を説明する。緯糸送り羽根調整工具４０は、ポリアセタールあるいはナイロン等の弾性変形可能な熱可塑性樹脂を素材として、射出成型等により形成され、本体４１及び本体４１に備えた本体装着部４２、４３、本***置決め部４４、４８、５２、緯糸送り羽根当接部４５から構成されている。本体４１は、測長バンド７の貯留部１０と同様に弧状に形成され、両端に本体装着部４２、４３を備えている。   4 to 6, the configuration of the weft feed blade adjustment tool 40 will be described. The weft feed blade adjustment tool 40 is formed by injection molding or the like using an elastically deformable thermoplastic resin such as polyacetal or nylon, and includes a main body 41 and main body mounting portions 42 and 43 provided in the main body 41, and a main body positioning portion 44. , 48, 52 and the weft feed blade contact portion 45. The main body 41 is formed in an arc shape like the storage portion 10 of the length measurement band 7, and includes main body mounting portions 42 and 43 at both ends.

本体装着部４２は、本体４１の端部から鉤形に屈曲して延びる引掛け部４６、引掛け部４６と本体４１の内周面５３との間に鉤状に形成された引掛け溝４７及び測長バンド７の貯留部１０の外周面に接触可能な湾曲面を有する本***置決め部４８から構成されている。引掛け溝４７は貯留部１０の周方向の端部を収容できる大きさに形成されている。本体装着部４３は、本体４１の外周面５４に接続した平らな面を有する操作部４９、操作部４９から鉤形に屈曲して延びる引掛け部５０、滑らかな傾斜面でＶ字状に形成された着脱溝５１及び測長バンド７の貯留部１０の外周面に接触可能な湾曲面を有する本***置決め部５２から構成されている。   The main body mounting portion 42 has a hook portion 46 that is bent and extended from the end portion of the main body 41 into a hook shape, and a hook groove 47 formed in a hook shape between the hook portion 46 and the inner peripheral surface 53 of the main body 41. And a main body positioning portion 48 having a curved surface that can come into contact with the outer peripheral surface of the storage portion 10 of the length measuring band 7. The hooking groove 47 is formed in a size that can accommodate the circumferential end of the reservoir 10. The main body mounting portion 43 is formed in a V shape with an operation portion 49 having a flat surface connected to the outer peripheral surface 54 of the main body 41, a hook portion 50 that bends and extends from the operation portion 49 in a bowl shape, and a smooth inclined surface. The main body positioning portion 52 has a curved surface that can come into contact with the outer circumferential surface of the storage groove 10 of the length measuring band 7 and the attaching / detaching groove 51.

本体装着部４３の操作部４９は、作業者が測長バンド７の貯留部１０に対する緯糸送り羽根調整工具４０の取付け、取外し操作を容易に行える形状に形成されている。着脱溝５１は、貯留部１０の周方向の端部を収容可能な大きさに形成され、貯留部１０との間で滑り易い形状に形成されている。このため、操作部４９に一定の圧力を掛けることにより本体４１が弾性変形し、測長バンド７に対する本体４１の着脱を容易に行うことができる。なお、本体４１を測長バンド７の貯留部１０に着脱可能とするために、本体装着部４２の引掛け溝４７と本体装着部４３の着脱溝５１との間の距離Ｌ１（図４参照）は、貯留部１０の周方向の距離Ｌ２（図５参照）と同一又は僅かに長くなるように構成されている。   The operation part 49 of the main body mounting part 43 is formed in a shape that allows the operator to easily attach and remove the weft feed blade adjusting tool 40 to the storage part 10 of the length measuring band 7. The detachable groove 51 is formed in a size that can accommodate the circumferential end of the storage unit 10, and is formed in a shape that is easy to slide between the storage unit 10. For this reason, the main body 41 is elastically deformed by applying a certain pressure to the operation portion 49, and the main body 41 can be easily attached to and detached from the length measuring band 7. In addition, in order to make the main body 41 detachable from the storage part 10 of the length measurement band 7, a distance L1 between the hooking groove 47 of the main body mounting part 42 and the mounting / removal groove 51 of the main body mounting part 43 (see FIG. 4). Is configured to be the same as or slightly longer than the circumferential distance L2 of the reservoir 10 (see FIG. 5).

本***置決め部４４は、本体４１の周方向に一定の幅の湾曲面を有するように、本体４１の周方向の中間位置において、内周面側（測長バンド７側）突出させた突出部で構成されている。本***置決め部４４の高さは、本***置決め部４８及び本***置決め部５２と同一に形成されている。また、本***置決め部４４、４８、５２の湾曲面は、同一の曲率半径で形成されている。従って、本実施形態では、３箇所に形成された本***置決め部４４、４８、５２により本体４１の位置決めを行っている。また、本***置決め部４４は、図５及び図６に示すように、緯糸送り羽根２７が出没する測長バンド７の挿通孔１３の間に位置する貯留部１０の一部と対向する位置に形成されている。   The main body positioning portion 44 is a protruding portion that protrudes from the inner peripheral surface side (measurement band 7 side) at an intermediate position in the circumferential direction of the main body 41 so as to have a curved surface with a certain width in the circumferential direction of the main body 41. It is configured. The height of the main body positioning portion 44 is the same as that of the main body positioning portion 48 and the main body positioning portion 52. Further, the curved surfaces of the main body positioning portions 44, 48, 52 are formed with the same radius of curvature. Therefore, in this embodiment, the main body 41 is positioned by the main body positioning portions 44, 48 and 52 formed at three locations. Further, as shown in FIGS. 5 and 6, the main body positioning portion 44 is formed at a position facing a part of the storage portion 10 located between the insertion holes 13 of the length measurement band 7 in which the weft feeding blade 27 appears and disappears. Has been.

緯糸送り羽根当接部４５は、本***置決め部４４より測長バンド７とは反対側に窪ませた内周面で構成され、緯糸送り羽根当接部４５は貯留部１０の外周面と同心の円弧で形成されている。図６に示すように、本体４１を測長バンド７の貯留部１０に装着した時、本***置決め部４４、４８、５２が貯留部１０に当接し、貯留部１０の外周面と緯糸送り羽根当接部４５との間に隙間Ｈが形成される。隙間Ｈは、緯糸送り羽根２７が貯留部１０の挿通孔１３から突出する量を規定する。従って、本***置決め部４４、４８、５２は隙間Ｈを形成する機能を有し、必要に応じて本***置決め部４４、４８、５２の高さを種々変更した本体４１を準備することにより、緯糸送り羽根２７の突出量の変更に対応させることができる。   The weft feed blade contact portion 45 is configured by an inner peripheral surface that is recessed from the main body positioning portion 44 on the opposite side to the length measuring band 7, and the weft feed blade contact portion 45 is concentric with the outer peripheral surface of the storage portion 10. It is formed with an arc. As shown in FIG. 6, when the main body 41 is attached to the storage portion 10 of the length measuring band 7, the main body positioning portions 44, 48, 52 abut against the storage portion 10, and the outer peripheral surface of the storage portion 10 and the weft feed blade contact A gap H is formed between the contact portion 45. The clearance H defines the amount by which the weft feed blade 27 protrudes from the insertion hole 13 of the storage unit 10. Accordingly, the main body positioning portions 44, 48, 52 have a function of forming the gap H. By preparing the main body 41 in which the heights of the main body positioning portions 44, 48, 52 are variously changed as necessary, weft feeding This can correspond to a change in the protruding amount of the blade 27.

緯糸送り羽根２７の突出量の調整について、以下に説明する。織物仕様の織り幅に基づいて緯糸Ｙの測長貯留量が定められるため、緯糸測長貯留装置では、貯留ドラム６の巻径が織り幅に応じて調整される。図１に示した緯糸測長貯留装置では、作業者はボルト２３を緩めて取付けブラケット２２とともに緯糸送り羽根２７を取外す。次に、作業者は、ボルト１２を緩め、測長バンド７を長孔１１に沿わせて貯留ドラム６の半径方向に移動し、円板部３に刻設した目盛５６に合わせながら、織り幅に対応した巻径となる位置でボルト１２を締め付け、固定する（図２参照）。貯留ドラム６は４片の測長バンド７により構成されているため、他の３片の測長バンド７についても同様の方法にて半径方向の位置決めを行う。   The adjustment of the protruding amount of the weft feed blade 27 will be described below. Since the length measurement storage amount of the weft Y is determined based on the weaving width of the fabric specification, in the weft length measurement storage device, the winding diameter of the storage drum 6 is adjusted according to the weaving width. In the weft length measuring and storing apparatus shown in FIG. 1, the operator loosens the bolt 23 and removes the weft feed blade 27 together with the mounting bracket 22. Next, the operator loosens the bolt 12, moves the length measuring band 7 along the long hole 11 in the radial direction of the storage drum 6, and adjusts the weaving width while matching the scale 56 engraved on the disk portion 3. The bolt 12 is tightened and fixed at a position corresponding to the winding diameter (see FIG. 2). Since the storage drum 6 is composed of four length measuring bands 7, the other three length measuring bands 7 are positioned in the radial direction in the same manner.

次に、作業者は、図４に示した緯糸送り羽根調整工具４０を測長バンド７の貯留部１０に装着する。具体的には、本体４１を持ち、図５に示すように、本体装着部４２の引掛け部４６が貯留部１０の内周面側に、また本***置決め部４８が貯留部１０の外周面側に合うように、引掛け溝４７を貯留部１０の一方の端部（図５、図６では左側の端部）に係合する。この状態で、作業者は本体装着部４３の操作部４９を押圧する。熱可塑性樹脂により成型された本体４１は弾性変形し、引掛け部５０が貯留部１０の内周面側に滑り込み、図６に示すように、着脱溝５１が貯留部１０の他方の端部（図５、図６では右側の端部）に嵌合する。なお、熱可塑性樹脂で構成された本体４１は硬度が測長バンド７よりも低いため、測長バンド７の表面を傷付ける恐れが無い。   Next, the operator attaches the weft feed blade adjusting tool 40 shown in FIG. 4 to the storage portion 10 of the length measuring band 7. Specifically, the main body 41 is held, and as shown in FIG. 5, the hooking portion 46 of the main body mounting portion 42 is on the inner peripheral surface side of the storage portion 10, and the main body positioning portion 48 is on the outer peripheral surface side of the storage portion 10. The engaging groove 47 is engaged with one end of the reservoir 10 (the left end in FIGS. 5 and 6). In this state, the operator presses the operation unit 49 of the main body mounting unit 43. The main body 41 molded by the thermoplastic resin is elastically deformed, the hook portion 50 slides toward the inner peripheral surface side of the storage portion 10, and as shown in FIG. 6, the detachable groove 51 is the other end portion of the storage portion 10 ( 5 and FIG. 6 is fitted to the right end). Since the main body 41 made of thermoplastic resin has a hardness lower than that of the length measuring band 7, there is no fear of damaging the surface of the length measuring band 7.

図６に示すように、本体４１が貯留部１０に装着されると、本***置決め部４４、４８、５２が貯留部１０の外周面に当接し、本体４１の位置決めが行なわれる。このため、貯留部１０の外周面の上方、特に、挿通孔１３の上方には、緯糸送り羽根当接部４５との間に隙間Ｈが形成される。そこで、作業者は、取付けブラケット２２の長孔２５にボルト２３を通し、取付けブラケット２２を取付けプレート２０に緩く仮止めする。   As shown in FIG. 6, when the main body 41 is attached to the storage unit 10, the main body positioning units 44, 48, 52 abut against the outer peripheral surface of the storage unit 10, and the main body 41 is positioned. For this reason, a gap H is formed above the outer peripheral surface of the storage unit 10, particularly above the insertion hole 13, with the weft feed blade contact portion 45. Therefore, the operator passes the bolts 23 through the long holes 25 of the mounting bracket 22 and loosely temporarily fixes the mounting bracket 22 to the mounting plate 20.

作業者は、さらに取付けブラケット２２を貯留ドラム６の半径方向に移動して、取付けブラケット２２に固定された緯糸送り羽根２７を貯留部１０の挿通孔１３に挿入する。緯糸送り羽根２７の先端が本体４１の緯糸送り羽根当接部４５に当接し、移動を阻止された状態（図６の仮想線で示した緯糸送り羽根２７参照）で、作業者は一方の手で取付けブラケット２２を保持しながら、他方の手でボルト２３を締め付け、取付けブラケット２２を固定する。   The operator further moves the mounting bracket 22 in the radial direction of the storage drum 6 and inserts the weft feed blade 27 fixed to the mounting bracket 22 into the insertion hole 13 of the storage unit 10. In the state where the tip of the weft feed blade 27 is in contact with the weft feed blade contact portion 45 of the main body 41 and is prevented from moving (see the weft feed blade 27 shown by the phantom line in FIG. 6), the operator can While holding the mounting bracket 22, the bolt 23 is tightened with the other hand to fix the mounting bracket 22.

緯糸送り羽根調整工具４０により隙間Ｈが正確に規定されているため、作業者は取付けブラケット２２を固定すれば、貯留部１０に対する緯糸送り羽根２７の突出量を正確に確定することができる。緯糸送り羽根２７の取付けが終了すると、作業者は本体装着部４３の操作部４９と引掛け部５０を持ち、測長バンド７の上方へ引き上げる。これにより、着脱溝５１の傾斜面が貯留部１０の表面を滑り、本体４１が上方へ弾性変形するため、本体装着部４３が貯留部１０の他方の端部から外れ（図５の状態）、本体４１は貯留部１０から取外される。   Since the gap H is accurately defined by the weft feed blade adjustment tool 40, the operator can accurately determine the amount of projection of the weft feed blade 27 with respect to the reservoir 10 by fixing the mounting bracket 22. When the attachment of the weft feed blade 27 is completed, the operator holds the operation part 49 and the hooking part 50 of the main body mounting part 43 and pulls them up above the length measuring band 7. Thereby, since the inclined surface of the attaching / detaching groove 51 slides on the surface of the storage portion 10 and the main body 41 is elastically deformed upward, the main body mounting portion 43 is detached from the other end of the storage portion 10 (state of FIG. 5). The main body 41 is removed from the storage unit 10.

他の３片の測長バンド７についても、緯糸送り羽根２７は同一の緯糸送り羽根調整工具４０を用いて貯留部１０に対する緯糸送り羽根２７の突出量が正確に確定される。このため、全ての測長バンド７において、緯糸送り羽根２７の突出量を同一に設定することができる。なお、緯糸送り羽根２７の取付け作業時は、回転軸１を手動にて回転し、緯糸送り羽根２７の取付け対象となる測長バンド７の位置でスリーブ１６を最も偏心した状態にし、緯糸送り羽根２７の取付けを行う。   For the other three pieces of the measuring band 7, the weft feed blade 27 accurately determines the protruding amount of the weft feed blade 27 with respect to the storage unit 10 by using the same weft feed blade adjustment tool 40. For this reason, in all the length measuring bands 7, the protruding amount of the weft feed blade 27 can be set to be the same. At the time of attaching the weft feed blade 27, the rotary shaft 1 is manually rotated so that the sleeve 16 is most eccentric at the position of the length measuring band 7 to which the weft feed blade 27 is to be attached. 27 is attached.

（第２の実施形態）
図７は第２の実施形態を示したもので、第１の実施形態と同一の構成については同一の符号を付し、詳細な説明を省略する。なお、第２の実施形態は、必要に応じて第１の実施形態で示した図１の構成を参照して説明する。第２の実施形態における緯糸送り羽根調整工具５７は、図７（ａ）に示すように、本体５８に本***置決め部５９、６０、６１、本体装着部６２及び第１の実施形態と同じ構成を有する緯糸送り羽根当接部４５を備えている。 (Second Embodiment)
FIG. 7 shows the second embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The second embodiment will be described with reference to the configuration of FIG. 1 shown in the first embodiment as necessary. As shown in FIG. 7A, the weft feed blade adjusting tool 57 in the second embodiment has the same configuration as that of the main body positioning portions 59, 60, 61, the main body mounting portion 62 and the first embodiment in the main body 58. A weft feed blade contact portion 45 is provided.

本体５８は、第１の実施形態と同様に、弾性変形可能な熱可塑性樹脂で一体成型されている。本体５８の内周面６３側において、本***置決め部５９は本体５８のほぼ中央部に突出部として形成され、本***置決め部６０、６１は本体５８の両端部に突出部として形成されている。本***置決め部５９、６０、６１の各突出部の表面は、図７（ｂ）に示した測長バンド７の貯留部６４の外周面と同一の曲率半径を有する湾曲面に形成されている。本***置決め部５９は貯留部６４の周面方向に幅広く形成され、中央部に本体装着部６２が設けられている。   As in the first embodiment, the main body 58 is integrally formed of an elastically deformable thermoplastic resin. On the inner peripheral surface 63 side of the main body 58, the main body positioning portion 59 is formed as a protruding portion at a substantially central portion of the main body 58, and the main body positioning portions 60 and 61 are formed as protruding portions at both ends of the main body 58. The surface of each protrusion of the main body positioning portions 59, 60, 61 is formed into a curved surface having the same radius of curvature as the outer peripheral surface of the storage portion 64 of the length measuring band 7 shown in FIG. The main body positioning part 59 is formed widely in the circumferential direction of the storage part 64, and the main body mounting part 62 is provided in the center part.

本体装着部６２は、本***置決め部５９から延出し、先端（図７の下方側）に鉤６５を有する２本の引掛け部６６により形成されている。鉤６５は、引掛け部６６よりも本体５８の周方向に幅広くして段差を形成し、先端に向けて先細りの形状に形成されている。また、２本の引掛け部６６は本体５８の周方向に間隔を空けて設けられ、鉤６５を把持することにより、仮想線で示すように、弾性変形可能である。   The main body mounting portion 62 is formed by two hook portions 66 extending from the main body positioning portion 59 and having a flange 65 at the tip (lower side in FIG. 7). The flange 65 is wider than the hook portion 66 in the circumferential direction of the main body 58 to form a step, and is formed in a tapered shape toward the tip. The two hooks 66 are provided at intervals in the circumferential direction of the main body 58 and can be elastically deformed as indicated by phantom lines by gripping the collar 65.

測長バンド７の貯留部６４には、中央に挿通孔６７が穿設され、その両側にそれぞれ３個の挿通孔６８が均等な間隔で穿設されている。また、緯糸送り羽根６９は６個の挿通孔６８にそれぞれ対応するように、取付けブラケット２２（図１参照）の水平部７０に固定されている。なお、貯留部６４の周方向における挿通孔６７及び６個の挿通孔６８の幅は同一に形成されているが、挿通孔６７は、他の挿通孔６８と異なる幅で形成しても構わない。また、本体装着部６２の２つの引掛け部６６の間隔は、挿通孔６７の幅よりも若干小さくなるように設定されている。   An insertion hole 67 is formed in the center of the storage portion 64 of the measurement band 7, and three insertion holes 68 are formed at equal intervals on both sides thereof. Further, the weft feed blade 69 is fixed to the horizontal portion 70 of the mounting bracket 22 (see FIG. 1) so as to correspond to the six insertion holes 68, respectively. In addition, although the width of the insertion hole 67 and the six insertion holes 68 in the circumferential direction of the storage portion 64 is formed to be the same, the insertion hole 67 may be formed with a width different from that of the other insertion holes 68. . Further, the interval between the two hooking portions 66 of the main body mounting portion 62 is set to be slightly smaller than the width of the insertion hole 67.

第２の実施形態において、貯留ドラム６（図１参照）の巻径変更に伴う測長バンド７に対する緯糸送り羽根６９の突出量の調整は次のように行われる。測長バンド７の径方向の位置調整後、作業者は緯糸送り羽根調整工具５７の本体５８を持ち、本体装着部６２の引掛け部６６の先端を測長バンド７の貯留部６４に形成された挿通孔６７に当て、強く押し込む。引掛け部６６は、幅広の鉤６５が図７（ａ）の仮想線のように弾性変形しながら挿通され、本***置決め部５９、６０、６１が貯留部６４の外周面に当接する。   In the second embodiment, the amount of protrusion of the weft feed blade 69 with respect to the length measuring band 7 accompanying the change in the winding diameter of the storage drum 6 (see FIG. 1) is adjusted as follows. After adjusting the radial position of the length measuring band 7, the operator holds the main body 58 of the weft feed blade adjusting tool 57, and the tip of the hook portion 66 of the main body mounting portion 62 is formed in the storage portion 64 of the length measuring band 7. Press against the insertion hole 67 and press it firmly. The hook 66 is inserted while the wide collar 65 is elastically deformed as indicated by an imaginary line in FIG. 7A, and the main body positioning parts 59, 60, 61 abut against the outer peripheral surface of the storage part 64.

引掛け部６６は図７（ａ）の実線位置に復元し、図７（ｃ）に示すように、鉤６５の段差部が貯留部６４の内周面に当接して本体５８は貯留部６４に装着され、本体５８の位置が固定される。本体５８が貯留部６４に装着されると、貯留部６４の外周面と本体５８の緯糸送り羽根当接部４５との間に緯糸送り羽根６９の突出量として規定される隙間Ｈが形成される。続いて、作業者は緯糸送り羽根６９を貯留部６４の内周面側から挿通孔６８に挿入し、緯糸送り羽根６９を緯糸送り羽根当接部４５に当接させた状態で、図１に示した取付けブラケット２２をボルト２３の締め付けにより取付けプレート２０に固定する。   The hook portion 66 is restored to the solid line position in FIG. 7A, and the stepped portion of the flange 65 abuts against the inner peripheral surface of the storage portion 64 as shown in FIG. The position of the main body 58 is fixed. When the main body 58 is attached to the storage portion 64, a gap H defined as the protruding amount of the weft feed blade 69 is formed between the outer peripheral surface of the storage portion 64 and the weft feed blade contact portion 45 of the main body 58. . Subsequently, the operator inserts the weft feed blade 69 into the insertion hole 68 from the inner peripheral surface side of the storage portion 64 and places the weft feed blade 69 in contact with the weft feed blade contact portion 45 in FIG. The mounting bracket 22 shown is fixed to the mounting plate 20 by tightening bolts 23.

緯糸送り羽根６９の取付けが完了すると、作業者は一方の手で鉤６５を把持し、引掛け部６６を図７（ａ）の仮想線のように弾性変形させながら、他方の手で本体５８を持ち上げることにより、貯留部６４から本体５８を取外すことができる。第２の実施形態では、本体装着部６２を本体５８の中央部に設け、測長バンド７の貯留部６４に形成した挿通孔６７を利用して本体５８を貯留部６４に装着した構成であるが、第１の実施形態と同一の作用効果を得ることができる。   When the attachment of the weft feed blade 69 is completed, the operator holds the hook 65 with one hand and elastically deforms the hook 66 as shown by an imaginary line in FIG. The main body 58 can be removed from the storage portion 64 by lifting up. In the second embodiment, the main body mounting portion 62 is provided in the central portion of the main body 58, and the main body 58 is mounted on the storage portion 64 using the insertion hole 67 formed in the storage portion 64 of the length measurement band 7. However, the same effect as the first embodiment can be obtained.

The third embodiment will be described with reference to the configuration of FIG. 1 shown in the first embodiment as necessary. As shown in FIG. 8A, the weft feed blade adjusting tool 71 in the third embodiment has the same configuration as that of the main body positioning portion 73, the main body mounting portions 74 and 75, and the first embodiment. A weft feed blade contact portion 45 is provided.

本***置決め部７３は、本体７２のほぼ中央部に突出部として形成され、本***置決め部７３の突出部の表面は、図８（ｂ）に示した測長バンド７の貯留部６４の外周面と同一の曲率半径を有する湾曲面に形成されている。本***置決め部７３は貯留部６４の周面方向に幅広く形成され、貯留部６４の中央の挿通孔６７に隣接する左右の挿通孔６８に達する長さを有する。また、本***置決め部７３の両端部は、緯糸送り羽根当接部４５と接続する湾曲面で形成された規制部７７、７８を構成する。規制部７７、７８の湾曲面は、緯糸送り羽根６９の先端部の湾曲面と同一又は近似した曲率半径を有するように構成されている。   The main body positioning portion 73 is formed as a protruding portion at substantially the center of the main body 72, and the surface of the protruding portion of the main body positioning portion 73 is the same as the outer peripheral surface of the storage portion 64 of the length measuring band 7 shown in FIG. It is formed in the curved surface which has the same curvature radius. The main body positioning portion 73 is formed widely in the circumferential direction of the storage portion 64 and has a length that reaches the left and right insertion holes 68 adjacent to the central insertion hole 67 of the storage portion 64. Further, both end portions of the main body positioning portion 73 constitute restricting portions 77 and 78 formed by curved surfaces connected to the weft feed blade contact portion 45. The curved surfaces of the restricting portions 77 and 78 are configured to have the same or approximate radius of curvature as the curved surface of the tip portion of the weft feed blade 69.

本体装着部７４は、鉤形に屈曲させた引掛け部７９及び引掛け溝８０から構成され、第１の実施形態における本体装着部４２の引掛け部４６及び引掛け溝４７と同一の機能を有し、詳細な説明を省略する。また、本体装着部７５は、本体７２の外周面８１に接続した平らな面を有する操作部８２、操作部８２から鉤形に屈曲して延びる引掛け部８３、滑らかな傾斜面を有するように湾曲して形成された着脱溝８４から構成されている。本体装着部７５の各構成部分は、第１の実施形態における本体装着部４３の操作部４９、引掛け部５０及び着脱溝５１と同一の機能を有し、詳細な説明を省略する。   The main body mounting part 74 includes a hooking part 79 bent in a bowl shape and a hooking groove 80, and has the same functions as the hooking part 46 and the hooking groove 47 of the main body mounting part 42 in the first embodiment. Detailed description is omitted. Further, the main body mounting portion 75 has an operation portion 82 having a flat surface connected to the outer peripheral surface 81 of the main body 72, a hook portion 83 that is bent and extended in a bowl shape from the operation portion 82, and a smooth inclined surface. It is composed of an attaching / detaching groove 84 that is curved. Each component of the main body mounting portion 75 has the same functions as the operation portion 49, the hooking portion 50, and the attachment / detachment groove 51 of the main body mounting portion 43 in the first embodiment, and detailed description thereof is omitted.

第３の実施形態における緯糸送り羽根６９の突出量の調整は次のように行われる。作業者は、緯糸送り羽根調整工具７１の本体７２を持ち、本体装着部７４の引掛け部７９が測長バンド７の貯留部６４の内周面に当接するようにして引掛け溝８０を貯留部６４の一端部に係合する。次に、作業者が本体装着部７５の操作部８２を強く押すと、本体７２が弾性変形して引掛け部８３が貯留部６４の他端部の内周面側に入り込み、着脱溝８４が貯留部６４の他端部に係合する。   Adjustment of the protrusion amount of the weft feed blade 69 in the third embodiment is performed as follows. The operator holds the main body 72 of the weft feed blade adjusting tool 71 and stores the hook groove 80 so that the hook portion 79 of the main body mounting portion 74 contacts the inner peripheral surface of the storage portion 64 of the length measuring band 7. Engage with one end of the portion 64. Next, when the operator strongly presses the operation part 82 of the main body mounting part 75, the main body 72 is elastically deformed, the hook part 83 enters the inner peripheral surface side of the other end part of the storage part 64, and the attachment / detachment groove 84 is formed. Engage with the other end of the reservoir 64.

作業者の一連の操作により、図８（ｂ）に示すように、本体７２が貯留部６４に装着される。本体７２は貯留部６４の外周面と当接する本***置決め部７３により位置決めされるため、貯留部６４の外周面と本体７２の緯糸送り羽根当接部４５との間に、緯糸送り羽根６９の突出量に相当する隙間Ｈが形成される。続いて、作業者は緯糸送り羽根６９を貯留部６４の内周面側から挿通孔６８に挿入し、緯糸送り羽根６９を緯糸送り羽根当接部４５に当接する。   As shown in FIG. 8B, the main body 72 is attached to the storage unit 64 by a series of operations by the operator. Since the main body 72 is positioned by the main body positioning portion 73 that contacts the outer peripheral surface of the storage portion 64, the weft feed blade 69 protrudes between the outer peripheral surface of the storage portion 64 and the weft feed blade contact portion 45 of the main body 72. A gap H corresponding to the amount is formed. Subsequently, the operator inserts the weft feed blade 69 into the insertion hole 68 from the inner peripheral surface side of the storage portion 64 and contacts the weft feed blade 69 with the weft feed blade contact portion 45.

この時、挿通孔６７に隣接する両側の挿通孔６８に挿通された２つの緯糸送り羽根６９は、先端部が本***置決め部７３の両側に形成された規制部７７、７８と接触する。このため、緯糸送り羽根６９は貯留部６４の周方向の振れを規制部７７、７８によって防止され、安定した状態で位置決めされる。作業者は、緯糸送り羽根６９を緯糸送り羽根当接部４５に当接させた状態で、図１に示した取付けブラケット２２をボルト２３の締め付けにより取付けプレート２０に固定する。   At this time, the two weft feed blades 69 inserted into the insertion holes 68 on both sides adjacent to the insertion hole 67 come into contact with the restriction portions 77 and 78 formed on both sides of the main body positioning portion 73. For this reason, the weft feed blade 69 is positioned in a stable state by preventing the swinging of the storage portion 64 in the circumferential direction by the restricting portions 77 and 78. The operator fixes the mounting bracket 22 shown in FIG. 1 to the mounting plate 20 by tightening the bolts 23 in a state where the weft feeding blade 69 is in contact with the weft feeding blade contact portion 45.

緯糸送り羽根６９の取付けが終了すると、作業者は本体装着部７５の操作部８２と引掛け部８３を持ち、測長バンド７の上方へ引き上げる。これにより、着脱溝８４の傾斜面が貯留部６４の表面を滑り、本体７２が上方へ弾性変形するため、本体装着部７５が貯留部６４の他方の端部から外れ、本体７２は貯留部６４から取外される。第３の実施形態では、第１の実施形態と同一の作用効果を得られるとともに、本***置決め部７３に設けた規制部７７、７８の構成により緯糸送り羽根６９を安定した状態で位置決めできるという作用効果を得ることができる。   When the attachment of the weft feed blade 69 is completed, the operator holds the operation portion 82 and the hook portion 83 of the main body mounting portion 75 and pulls them up above the length measuring band 7. As a result, the inclined surface of the attaching / detaching groove 84 slides on the surface of the storage portion 64 and the main body 72 is elastically deformed upward, so that the main body mounting portion 75 comes off from the other end of the storage portion 64, and the main body 72 is stored in the storage portion 64. Removed from. In the third embodiment, the same operational effects as the first embodiment can be obtained, and the weft feed blade 69 can be positioned stably by the configuration of the restriction portions 77 and 78 provided in the main body positioning portion 73. An effect can be obtained.
